# 20211025 bkw:
# - updated for v1.22.
# - new icon, new-style icons.
# 20200927 bkw: updated for v1.21.
# 20191127 bkw: updated for v1.20.
# 20180611 bkw: updated for v1.20.
# 20170316 bkw:
# - updated for v1.17.
# - use github for download (saves bandwidth, the homepage's zip file has
#   windows exes and dlls in it).
# - don't include README.md (it just says 'see Readme.txt').
# - update man page (new 1.17 options).
# - update wrapper script to support both system-wide and per-user mods.
